[0029] like Figures 1 to 7 As shown, the utility model provides a wing-free transition section guardrail, which is arranged between a bridge guardrail 1 and a highway guardrail 2. The wing-free transition section guardrail includes a first bracket 3, a second bracket 4 and at least one group of first columns 5.
[0030] See also Figure 1 and Figure 2 In an embodiment of the present application, the bridge guardrail 1 is a concrete guardrail, and the highway guardrail 2 is a two-wave guardrail. The first column 5 is installed on the earth roadbed, and the first column 5 can be set to multiple. In some embodiments of the present application, multiple first columns 5 are arranged at equal intervals between the bridge guardrail 1 and the highway guardrail 2. Among them, the first column 5 adjacent to the bridge guardrail 1 is 750mm away from the end face of the bridge guardrail 1. The first bracket 3 is made of steel pipe, and specifically, the first column 5 is made of high-strength steel with a yield strength of not less than 670GPa.
[0031] The first column 5 is provided with a corrugated anti-collision plate 6, which is a facility used for road protection, and is usually wavy or convex in shape to absorb collision energy to protect the roadway and vehicles.
[0032] In this embodiment, the corrugated anti-collision plate 6 is preferably made of a three-corrugated beam plate. The three-corrugated beam plate is used in places that require high-strength protection, such as highways and urban roads. The guardrail beam made of the three-corrugated beam plate has high impact resistance and deformation resistance, and can effectively protect roads and vehicles.
[0033] The first end of the corrugated anti-collision plate 6 is connected to the bridge guardrail 1 through the first bracket 3, and the second end of the corrugated anti-collision plate 6 is connected to the first column 5 through the second bracket 4. The first end of the corrugated anti-collision plate 6 is connected to the bridge guardrail 1 through the first bracket 3, so that the corrugated anti-collision plate 6 is partially away from the side of the concrete guardrail, increasing the buffer space for the lateral deformation of the guardrail and reducing the resistance of the end of the bridge guardrail 1 to the wheels.

A first mounting plate 32 is provided at the first end of the main body 31, and the first mounting plate 32 is connected to the first column 5. Since the first bracket 3 is made of steel pipe, the corrugated anti-collision plate 6 is made of three-wave beam plate, and the bridge guardrail 1 is a concrete guardrail, the steel pipe is more rigid than the steel plate, which can increase the longitudinal rigidity of the crossbeam, which is beneficial to the transition guidance of the semi-rigid guardrail such as the two- and three-wave beam guardrail and the rigid guardrail (concrete guardrail).
[0035] A second mounting plate 33 is provided on one side of the second end of the main body 31, and the second mounting plate 33 is connected to the first transition guardrail 61.

The first bracket 3 is connected to the bridge guardrail 1 and the first column 5, which can increase the strength of the first column 5 and reduce the lateral tilt amplitude of the first column 5 when a collision occurs, which is conducive to enhancing the anti-collision function of the guardrail.
[0036] In order to make the transition between the corrugated anti-collision plate 6 and the bridge guardrail 1 smoother, in some embodiments of the present application, a first transition guardrail 61 is provided on the first end of the corrugated anti-collision plate 6, and the first transition guardrail 61 is connected to the bridge guardrail 1. Specifically, one end of the first transition guardrail 61 overlaps with one end of the corrugated anti-collision plate 6, and the other end of the first transition guardrail 61 overlaps with the bridge guardrail 1. The overlapping method can be welding overlap or bolt overlap, and the present application adopts bolt overlap as a preferred embodiment.

Specifically, one end of the second transition guardrail 62 overlaps with the other end of the corrugated collision plate 6, and the other end of the first transition guardrail 61 overlaps with the highway guardrail 2. The overlapping method can be welding overlap or bolt overlap, and the present application adopts bolt overlap as a preferred embodiment.
[0038] See also Figures 1 to 5 In order to prevent the small car from slipping out of the bottom of the guardrail connecting section and falling into the water, in an embodiment of the present application, a protective beam 7 is also provided on the first column 5. The protective beam 7 is made of a two-wave beam plate. The protective beam 7 can prevent the small car from rushing out of the guardrail during a collision.
[0039] In the embodiment of the present application, a third bracket is further included, and the protection beam 7 is connected to the first column 5 through the third bracket.

A baffle 715 is provided on the opening 714 formed by the transition beam 711 and the first mounting portion 712.
[0041] The utility model provides a wing wall-free transition section guardrail, wherein the first end of the corrugated anti-collision plate 6 is connected to the bridge guardrail 1 through the first bracket 3, so that the corrugated anti-collision plate 6 is partially away from the side of the concrete guardrail, increasing the buffer space for the lateral deformation of the guardrail and reducing the resistance of the bridge guardrail 1 end to the wheel. The first bracket 3 is made of steel pipe, and the corrugated anti-collision plate 6 is made of three-wave beam plate. The bridge guardrail 1 is a concrete guardrail. The steel pipe has higher rigidity than the steel plate, which can increase the longitudinal rigidity of the beam, and is beneficial to the transition guidance of semi-rigid guardrails such as two- and three-wave beam guardrails and rigid guardrails (concrete guardrails). The first column 5 is installed on the soil roadbed. The concrete guardrail has higher anti-overturning strength than the first column 5 set on the soil roadbed. The first bracket 3 is connected to the bridge guardrail 1 and the first column 5, which can increase the strength of the first column 5 and reduce the lateral inclination amplitude of the first column 5 when a collision occurs, which is beneficial to enhancing the anti-collision function of the guardrail. The present invention has a simple structure, is easy to install, and has a short construction time. It effectively replaces the function of the wing wall. At the same time, when a collision occurs, it can effectively guide the colliding vehicle out to avoid more serious traffic injuries.
